I would think yes. I sued it to cut limestone and it did it with ease.
I would say yes. 11/4 is about as deep of a cut as you will get with this 4.5 inch blade. Any deeper and you will need to go to a 6 or 8 inch blade.
Yes it will. But it's usually used for irregular cuts or cuts that'll be hidden. It's hard to get a clean straight cut. A wet saw is better for those, which you can rent. But if you do use this blade, it'll be dusty, so be prepared and definitely use your PPE. You can use water to reduce the dust. Take your time and practice because it can get away from you in a hurry, especially if you don't have a variable speed grinder. Cheers!
No. Type 1 (FLAT).Type 27 has a bell curve, recessing the nut. Type 29 has the edges turned up a bit along with the bell curve. By the way, as long as you keep the nut out of your work, the type 1 will work fine after the housing around the blade is removed. (I need the whole outside of the grinder and remove the blade housing before installing a blade). If safety is an issue, keep it on and use type 27. I have not seen a type 27 diamond grinding wheel.
Not effectively, no
Yes you can.
Yes, it is possible to use this blade to cut porcelain. The porcelain might chip though.
My ryobi says same, but I used this on it no problem. Even fit with the guard.
Surprise!! you're engaged moron. It's for different sized shafts on your grinder which I hope you don't own because you will definitely cut your finger off
